Nonlinear earthquake respond analysis of soil is carried out to obtain ground acceleration and yield acceleration time history , in which the law of pore pressure in saturated sand is used to revise the yield strength of soil and the strain - stress relationship of soil is assumed to be rigid plastic in every time - internal . appling the model of newmark ' s rigid slide block , the lateral displacement induced by liquefaction during earthquake is calculated and the possible factors which may influence the large ground displacement are well studied 通過對土體進行非線性地震反應分析,引入地震過程中飽和砂層中孔隙水壓力生成的經驗公式,利用這一公式在各時段內對土的抗剪強度進行修正,假定每一時段內土的應力-應變關系為剛塑性,求出該時段內的地面加速度時程和屈服加速度時程,然后根據newmark剛性滑塊的基本原理,計算地震過程中由液化產生的地面側移值,并對影響地面大位移的各種可能因素進行了詳細的研究。

In this paper , based on the analysis of the rlem of theory foundation , computing method , preference , applicability , etc , we anatomized the rlem of three self - deficiencies and six scarcities . moreover , we adopted the parallel ways of contrasting the rlem with the fem and applied it to analyzing the impact of slide block of elasticity and plasticity , slip surface of coefficient and slip bed of elasticity , plasticity upon the stability of slope and in the plain linearity slope , the plain refracted line slope and the plain arc slope . in addition , we discussed the warp of between the lem of ( sarma , janbu , order , bishop , morgenstera - price , etc ) and the fem of result and the distributing of positive stress and shear stress on the slip surface 本文從剖析剛體極限平衡法的理論基礎、計算方法、參數選取、適用條件等方面入手,剖析了剛體極限平衡方法的3點自身缺陷和6點不足,并在此基礎上采用了剛體極限平衡法(平面滑動破壞法、 sarma法、傳遞系數法、普遍條分法、 janbu法、 bishop法、 morgenstern - price法)與大型有限元法對比研究的方法,分析研究了平面直線型滑坡、平面折線型滑坡、平面圓弧型滑坡在漸進破壞中邊坡的滑體彈塑性參數、滑面塑性參數) 、滑床的彈塑性、以及極限平衡法無法考慮開挖應力釋放等因素對邊坡穩定性的影響與滑動面上的正應力、剪應力分布規律、安全系數的解答的差異。

For jiangpinghe double - curved arch dam , 3 - d elasto - plastic fem is made , in which the point safety factors of the dam - abutments system and the safety margin for coefficients of sliding resistance on 7 potential sliding blocks of the dam before and after the reinforcement of the dam are calculated under the conditions of the normal storage level and the design flood level respectively based on the results from the analysis made with fem 摘要對江坪河雙曲拱壩進行了三維彈塑性有限元分析,利用有限元應力成果分別計算了正常蓄水位、設計洪水位等3種工況下加固前后壩體壩肩系統的點安全系數和7個可能滑動塊體的抗滑富余系數。

The at 2 scale based on the internal area - time lower bound of the viterbi decoder is analyzed . and the at 2 scales of three vlsi realization algorithms ( m - step decoder algorithm , flow and block decoder algorithm , and sliding block decoder algorithm ) are deduced . in succession , a fully new algorithm named ring - vd algorithm designed by ourselves is put forward , and its at 2 scale is also fetched 分析并推導了viterbi譯碼器基于內部信息流的vlsi面-時下界at2尺度;推導了已有的三種viterbi譯碼器的vlsi高速實現算法( m步譯碼算法、流水式塊譯碼算法和滑動塊譯碼算法)的at2尺度;提出了一種新的環形vd算法,并推導了它的at2尺度;對四種viterbi譯碼器的vlsi高速實現算法進行了比較分析。

We have been closely cooperated with beijing institute of technology , one of the most prestigious university in china , and co - developed ion vacuum plating technique , multi - arc tin coating technique and twin - eccentric automatic fuel supply advancer in the recent years successively , and acquired many patents . the sag and scda series fuel supply advancer manufactured in one of our branch company : has adopted the advanced twin - eccentric blocks structure , thoroughly changed the traditional structurearc block , sliding block . the angle of advance is very accurate and precise , also perfect at position resume 由本總公司提前器廠生產的sag scdm兩大系列供油角度自動提前器,改變了目前提前器市場上的傳統結構,用先進的雙偏心式結構,代替了二十年一貫制的弧形塊滑塊式結構,具有提前角特別靈敏,恢復性好,怠速運轉無噪音等優點,克服了提前器擺動大漏油等常見缺陷。

In the text , differential coefficient method and numerical value differential coefficient method have been introduced for crank slide block machine accuracy analysis , and influence of the fitting clearance of moving pair to component moving error has been given 文章介紹了微分法及數值微分法曲柄滑塊機構精度分析,說明了運動副的配合間隙對構件運動誤差的影響。

On basis of the calculation method of residue sliding force , the transfer coefficient method is improved to obtain the slide block balance method , the application scope of which is wider 在滑坡剩余下滑力的計算方法上,改良傳遞系數法,提出了精度更高,適用范圍更廣泛的廣義不平衡推力法。

We liked the poses on show here , many of which are all the better because a multi - part or sliding block mould has been used to improve the position of the man and remove excess plastic 這些兵人的姿勢都很不錯,采用新的開模技術使得姿態得到提升并且移除了多余的塑料。

The presented insulating lift adopts the traditional scissor structure , and is actuated by the master - slave voussoir and horizontal slide block with relay style 該絕緣升降平臺采用傳統的剪叉式結構,以及絕緣主從楔塊驅動和水平驅動相互接力交替作用的驅動方式。

The sarma method and the push method employ supposed sliding faces and sliding blocks , though they consider structure faces Sarma法和不平衡推力法,雖考慮了結構面的存在,但是存在更多人工修飾的假定滑面和滑塊。
